So this means that kde is working ok, that is the .ps output is valid. I
had problems w/ apps that put out invalid .ps in the past. This is not the
case here.

I suspect that there is a problem w/ the printer config under cups.
However, did you say that some jobs were able to print? Sorry, I was not
sure. I thought you meant that only certain pages, such as asp could not
print. Is this true? From what I know about this now, I'm guessing pure
html would be a problem as well. Just a guess.

I looked at the file and it looks great, well as good as .ps files do
under gs. :)

I'm assuming you have an HP laser printer. Right? This is good news, as
these printers are dead easy to configure and debug under linux (compared
w/ inkjets).

Here are my guesses for now:

1. Printer is not configured correctly. Test: can you print _any_ .ps
files properly? If yes, then which ones? How do printable ones differ from
non-printable ones?

2. Level of .ps is not compatible w/ the printer you are using. This one
bit me. The .ps standard has a few levels. I force all my output to level
1 as I have a cheap laser printer.

Answer a few more questions and maybe we can get further with this one.
